WOVEN-mn Inmo.

My invention relates to an improvement in woven wire fabric, and particularly to improved means .for marking this fabrlc in designatedv lengths to assist in marketing the l material. My invention will be more readdescripily understood from the following t e accomtion thereof in-connection with panying drawings, in which- Figure 1 is' a perspective v-iew of a roll of woven wire fabric embodying the features of my invention. Figure 2 is an'enlarged detail showing the manner in which the fabric is marked.

. In the'drawing, I have shown a strip 3 .15 of woven wire fabric which is marked at designated intervals by a distinctive marking, so that a predetermined length of this material can be quickly and readily measured ofi'. In order to provide a marking which will not only be clearl visible but substantially permanent and w ich will enable the fabric to be rolled up' shortly after marking, I have devised the following'im- "proved method of marking this fabric: I

A first forces suitable tool through one of` the meshes of the wire, thus forcing apart the strands of the wire fabric which surround this opening indicated as 4 in the.

drawing, and in this manner the strands' of wire 5 which surround the opening are brought in closer juxtaposition than the normal strands 6 of the fabric. The marginal portion of this opening of which the strands are thus forced in closer relationship is then Vmarked -by means of a quick drying paint 7 of a contrastingand distinctive color, 'which paint owing to its viscosity and surface tension spans the space between the adjacent strands of wire, thus 40 -forming a marking which is easily and distinctlv visible. By reason of the quick drying character of the paint which is preferably composed of a compound of gun cotton, alcohol and amyl acetate, the fabric can be Aapplication mea my as, im. semi in. mms.

vquickly rolled without danger of the 4 aint 45 sticking. Furthermore, by reason o the fact that the aint completely fills the intersticas inthe abric surrounding the opening,

-this paint is applied in sufficient quantities so as to be easlly visible, and by reason of the strands of wire being forced into closer proximity where the paint is applied, this paint adheres more firmly to the wire strands of the fabric and thus themarking is more permanent.

While I have illustrated and described one specific embodiment of my invention, it will be understood that I do not wish to be limited tothe exact form of the invention shown and described, but thatvarious 60 changes and modifications ma be made without departing from the spirit and in tent of m invention.

What claim as my invention is:

1. A web of wire "screen lcloth having, 6 5 measure marks at redetermined distances and adjacent the e ge thereof, each of said measure marks consisting of an enlarged opening formed by a separation of adjacent wires and a film of' marking medium bridg- 70" .ing across and filling the openings between -the wires around said enlarged opening.

2. A rocess of applying measure marks to a we of wire screen cloth which comprises the operations of forcing a tool between the wires at predetermined intervals thereby forming an enlarged opening and crowdlng the wires surrounding the opening into'closer proximity, and applying a quickdrying viscous marking medium to the screen around said opening thereby causing said medium to bridge across and ll the openings between the wires in the space immediately surrounding said enlarged opening.
